Use the quadratic formula to find the solution(s) of \( \frac{1}{2}x^2 - 3x + 4 = 0 \).
\( x = 2 \)
none
\( x = 4 \)
\( x = -4 \)
\( x = -2 \)

Answer

To solve \( \frac{1}{2}x^2 - 3x + 4 = 0 \) using the quadratic formula, we first identify \( a = \frac{1}{2} \), \( b = -3 \), and \( c = 4 \).

The quadratic formula is \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \).

Calculate the discriminant: \( b^2 - 4ac = (-3)^2 - 4 \times \frac{1}{2} \times 4 = 9 - 8 = 1 \).

Since the discriminant is positive, there are two real solutions:

  1. \( x = \frac{-(-3) + \sqrt{1}}{2 \times \frac{1}{2}} = \frac{3 + 1}{1} = 4 \)
  2. \( x = \frac{-(-3) - \sqrt{1}}{2 \times \frac{1}{2}} = \frac{3 - 1}{1} = 2 \)

Therefore, the solutions are \( x = 4 \) and \( x = 2 \).

Correct options: \( x = 2 \), \( x = 4 \)
